换个浏览器呢？使用chrome

3

推荐使用chrome； 检查下防火墙

4

抱歉，其他事耽误没有及时回复，更换chrome后，grafana的界面已经能够打开，但是没有任何数据，尝试采用Tidb 3.0的版本，grafana.log日志的报错任然包含很多“Alert Rule returned no data”，然后尝试检查node_exporter.log发现很多关于CPU的error，搜索难找到相关信息,不确定是否有影响。

更换浏览器后，能打开grafana,但是没有任何数据，还说存在问题。

6

更换数据库版本后的grafana.log日志。

通过日志看是/sys/bus/cpu/devices/cpu0/cpufreq/scaling_cur_freq 这个文件不存在。解决思路： 1、先排查下这个文件为什么不存在。 2、对照着部署文档，看看哪几步存在疑点。
